The Voice of Nature (aka The Black-Mud Swamp)

The girls are on a field trip to practice the skills to ""listen to nature."" In the meanwhile, Nutt tells the witches that a few specialists are escorting the troll to Magix. Fearing that a mind sorceror might get a hold of the troll and discover their plan, they break the troll out. The specialists and fairies team up to find the troll, but the witches beat them to it and make the troll disappear forever. With no sign of the troll, the specialists head back to Red Fountain and the girls return to their class.
